This patch allows to emulate the STM32L4x5 EXTI device. It implements register access and software interruptions.
This is RFC since we had troubles to make all tests pass. More precisely, the line `g_assert_true(get_irq(GPIO_0_IRQ));` fails in the software interrupts test. No irq seems to be fired. (We also tested the stm32f4_exti (on which this implementation is based upon) on but it also fails so don't really know if the test or the implementation is incorrect) Based-on: <170049810484.22920.61207457697187832...@git.sr.ht> ([RFC v3 2/2] hw/arm: Add minimal support for the B-L475E-IOT01A board) (We got the message id from https://patchew.org/QEMU/170047309499.17129.498620900967978910...@git.sr.ht/ but don't really the standard procedure to get it.
